Trip Report: 13,501' Mt. Thompson - "Knudston Couloir" in Powder Snow

Summary by SnowBrains
Report from April 30, 2026 I arrived in Mammoth Lakes, CA, on April 28th – earlier than I’d ever arrived for my spring foray in the Eastern Sierra. There was powder in them hills. I was told to go high and north and find something untracked. I knew that Mt. Thompson had 4 or 5 chutes on it delivering a good chance that at least one of them would be fresh. The plan was to roll solo, then the legendary Jason Dobbs showed up… Lake. Image: SnowBrain…
